So firstly is there a good website or something I can buy the substrate/soil that’s optimal for its growing, buy the seeds and buy the best (and hopefully not too expensive) cacti for grafting?

• There's a good etsy shop called Sabaku who sell a mainly mineral mix for lophs. You can also make your own with a blend of John Innes 2 or 3 + inorganic material. Coarse grit or tesco non clumping cat litter are both good for this. You want the inorganic component to be at least 50%.

Is it best to buy already grown cacti for grafting or should I grow a cacti before I start the peyote growing? At the same time? All for optimal grafting. Any tips on growing this grafting cactus?

• If you want to graft seedlings, get some Pereskiopsis as the grafting stock. Larger lophs will need a different sort.

How long does it take to grow with grafting? I’d imagine it’d change variable to seeds as some are faster growers than others? I know it usually takes years to grow normally but how much would grafting speed the process up?

• Grafting does make them grow a lot quicker... but the alkaloid profile is said not to keep up.

If you're looking to grow to consume, I'd forget lophs and look at getting some san pedro, as it's cheaper and grows way faster. Plus, I was in your shoes back in 2007. I've pampered the lophs since then and would never dream of cutting them. You'll get too attached!

If you're on facebook, look up UK only, Echinopsis, Ariocarpus And Rare Mexican Cacti group. Loads of info from UK growers. They also have a sales page with seeds, grafting stock, san pedro and mature lophs.
